LibSass.x64 not found on Azure VM (virtocommerce)

Question

I new to ASP.NET development and I have managed to deploy VirtoCommerce to my local machine IIS (windows 8.1) following the documentation on http://docs.virtocommerce.com/display/vc2devguide/Deploy+web+applications+to+dedicated+server .

When I tried to deploy it in Azure VM running Windows server 2012, I got the following error when I tried to run the frontend page. The dll mentioned below is definitely in the /bin folder of the store.

Server Error in '/' Application. Could not load file or assembly 'LibSass.x64' or one of its dependencies. An attempt was made to load a program with an incorrect format.**

I followed the link Could not load file or assembly 'LibSass.x64' or one of its dependencies in VirtoCommerce but found no luck. What did I miss on this deployment ? Any help is much appreciated, thank you.

Answer 1

Are you running 64 but machine and IIS Application Pool as 64 bit? If not, make sure to go to IIS and configure pool settings to run as 64 bit process. The easier approach will be to follow the guide here: http://docs.virtocommerce.com/display/vc2devguide/Deploy+from+GitHub+to+Microsoft+Cloud+Azure which will setup Virto Commerce as a website in IIS with all correct configuration for IIS. You can then update it manyally by simply uploading site through FTP if you want. You can also clone the repository on GitHub and that way your azure site will auto update on every checkin.

I was able to reproduce this error on a clean Windows Server 2012 Standard. It turned out that Libsass.Net requires Visual C++ Redistributable Packages for Visual Studio 2013. After installing the vcredist_x64.exe the error has gone.
